Right.

The reason newer engines have it is nothing to do with acceleration, power or anything as brutish, masculine, or "mine performs better than yours" It is purely and simply to get round emission laws. Emission laws have now got tight enough to almost ban carbs. The engine must run clean across a wide power range and over a large part of it's life. Carbs have difficulty delivering the right mixture across a wide range and do go out of adustment, so FI is the answer. The ECU can control the FI unit far better than any mechanic with a screwdriver ever could with a carb.

It does pave the way to then have electronic throttle controls, which do a lovely job in smothing engine performance across the power band blah, blah. blah.



I'll put my head back down now.
